Simon For billing have a look at pmacct. It's very stable, reliable and accurate. <from the website> pmacct is a small set of passive network monitoring tools to measure, account and aggregate IPv4 and IPv6 traffic; aggregation revolves around the key concept of primitives (VLAN id, source and destination MAC addresses, hosts, networks, AS numbers, ports, IP protocol and ToS/DSCP field are supported) which may be arbitrarily combined to build custom aggregation methods; support for historical data breakdown, triggers and packet tagging, filtering, sampling. Aggregates can be stored into memory tables, SQL databases (MySQL or PostgreSQL) or simply pushed to stdout. Data is collected either using libpcap (and optionally promiscuous mode of the listening interface) or reading Netflow v1/v5/v7/v8/v9 packets coming from the network. </from the website> http://www.ba.cnr.it/~paolo/pmacct/ for more info You can do extremely powerful analysis on the captured data, give it a shot!
